Question

43. The distance moved by car P during the time interval in which they cross each other is
(1) 40 m
(2) 10 m
(3) 220 m
(4)
36 m​

Answer 1

(1) 40 m

Explanation:

Vp = 10 m/s

Vq = 15 m/s

Length of each car = 5m

The cars cross each other at time 5.

Just after crossing P covered (x + 5) m and Q covered (95-x) m

Vp = distance /  time =  x+5/t

Vq = 95-x / t

So x+5/10 = 95-x / 15

x = 35m

So the car would have covered 40 m.

Option 1 is the answer.
